To on whom may concern:

Be it known that I, WILLIAM W. WILsoN,v

a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented. certain new and of which t e following is a speci cation.

The object of my invention is to provide im roved means where y it will be im osof an adding mac ine tion with the printing mechanism. It sometimes happensthat in the useof adding machines, as now constructed, the operator will move the paper carriage out of operative relation with the printin mechanism for the urpose of inspecting t e work-previously one, and upon resumin operations will impress a number upon the eyboard of the machine and pull'the operating handle before restoring the paper carriage to operative position. The effect of this is to enter a number in' the accumulator of the adding machine 'without printin said number. This leadsto a discrepancyietween the total registered by the machine and the actual total of the printed list. In order to overcome this source of inaccuracy I have devised an improved machine whereby it is imssible to enter a number-in the accumu-.

atorof the adding machine when the carriage'is moved out of cooperativefrelationmechanism.

the drawingsigune' I is :a sectional view of the parts of an addin machine to which my invention is applie Fig. 2-is a cross sectional view from the rear of the machine .Figs. 3 to 6, inclusive, are detail views.

I have illustrated my improvement applied to the Universal adding 'machinasee prior Patent 751,207,1ssue February 2,

I 1904, on the invention of F. .C. Rinsche.

The frontrail .1 of a paper carriage such as shown in said patent-carries a pro ecting part designated to cooperate with the lever 3, which is pivoted at 4 upon the. frame of The lever 3 is provided with the machine.

5 with which the carria e of a projection the machine directly cooperates. The ever lever 11 and permitting enerallyby the numeral 2,

3 is pivotedat 6 to dowhwardly projecting plunger 7, which is slidably mounted and adapted to move in a vertical. direction. Thelower end in the frame of the machine,

ofthe plunger 7 cooperates with the upper end of a slide 8' which moves in a guide 9 attached to the front frame of the machine. The slide 8 is normally impelled upwardly by-means of a coil-spring 10 attached at its lower end to the arm 8 and at its upper endfto the frame of the machine. A lever 11 is pivoted at 12 to a fixed part of the.

machine and at itsrear end is pivoted at 13 to the lower end of the slide 8. The stem 14: of an eliminating key 15 is provided with a projecting stud 16, and the forward end of the lever 11 bears upon the upper side of'said stud.

The projectingflange width of the carriage. is in its lowered position the part 2 will contact with the upward extension 50f the lever 3 and depresses the same, thus carrying the plunger 7 downwardly against the u per end of the slide 8. This has the e ect of. elevating the forward end of the 2 extends the entire to rise to its normal inactive position, thus permitting'all items to be entered in 'the accumulator. Whenever the carriage is raised, however, pressure will be removed from the lever 3 and the sprin the slide 8 upwardly, thus forward end of the lever 11 an with It the eliminating key; The depression of the eliminating key rotates the bell crank lever 19, which is pivoted at 20 upon the slide 21 beneath the forward end of the lever 22.

" The lever 22 is pivoted at 23 to a fixed part of the machine and is oscillated lag the cam 24, which is mounted upon the sha 25. The shaft 25 is oscillated'at each movement of the operating imparting movement to the lever 22. When theeliminating key is depressed therefor, the forward end of the lever 22 through its contact with the hook IQvvill carry the slide 21 downwardl The lower end of the slide 21 is connecte 'tothe bar 27, which operates the cam 28. Thecam 28 in the Universal maehine asnow upon-'the market, (see part the eliminating key e ressing the handle of the machine, thus When the carriage p 'lOwill dra-w '17 upon its pivot 18, thus thrusting the hook appears in Fig. 1 y 40, said"r.ackgbeingepivoted as usual to a 88 in said sliding bar 41 and ing slotted to receive a cross-rod- 42 of a bail'43 which has a stud 44 with the gages the-stud 30 upon tion 2 continuous,

-' lowered position.

engaging the cam slot of the piece 28. The adding gear which cooperates with said rack is desi ated by the numeral 45 and the correspon ing' display wheel by the numeral 46, the latterhavi a pinion 47 in mesh car 45. 'l fie upper side of the bar 27 is notc ed as shown-at 28'. When said bar 27 is in its elevated position the notch 28 enthe cam 28, thereby causing said cam to oscillate upon each movement of the operating handle, thus raising the racks into engagement with the accumulator gears. en,- however, the eliminating key is depressed the bar 27 is moved down-, ward to the osition shown in dotted lines in Fig. 1, said bar 27'will' oscillate forward and back without imparting movement to the cam 28. This has the efiect of rendering the racks inactive;-

ressed upon the keyboard to be eliminated cm the; accumulator. I have shown the pro'ecting bar 2 as r0- vided with a notch 32, t e purpose of which is to permit the lever 3 to Zrise..when the carriage is in such a position that said notch 32 is opposite the projection 5. This will have the effect of causing the elimination of all items entered in the machine when the carriage is in this position regardless of whethenthe carriage is raised or lowered. The function of this construction is to cause the elimination from the accumulator of all items printed in a certain columns This, however, is an independent feature of my construction and I. have rprovided means for rendering the lower 'su ace of the projecthus causing the accumuwhen the carriage is in its The means for rendering 'the lower edge of the rejection 2 continuous consists in a block 34. This block is moved in and out of the notch 2 b means of a screw 35 provided with an e ar ed end lation'of all items '36 engaging a recess in said bloc The screw 35 engages a threaded aperture in the yoke 36, which forms part of the pro'ection By turning the screw inwar ly the block 34 will obstruct the groove 2.

While .I have shown one s ific embodiment ,ofemy invention it'wil that the result may be accomplished in'varicue-ways dependent upon the particular constructionof the mechanism'to which the invention is applied. I, therefore, do not consider that my invention is limited to the .specfic 'mechanism -here"n,;or to its application to any particular 'form of adding machine, but that it includes and a paper carriage thus causing items im-- disabling the be apparent shown and described broadl the mechanism defined 'in the apms not printed is prevented. I claim: 1. In a machine of the character described, the combination with adding mechanism movable into and out sition; of. means for automatiof elfectlve call disabling the adding mechanism when sai paper carriage is out of such ppsit-ion, said means comprising a depress] le key and connections the carriage.
